Isolate bidi directionality changes to a single text.

See merge request lyskom-elisp-client/lyskom-elisp-client!15

* view-text.el (lyskom-print-text): Insert a paragraph separator if
  the bidi directionality was changed by the text.

Fix Emacs 27.1 incompatibility in lyskom-subtract-one-day

See merge request lyskom-elisp-client/lyskom-elisp-client!14

Keep any sub-second time elements unchanged, so that we return a valid
time format in lyskom-subtract-one-day.  Emacs 27.1 expects it to be
on the (HI LO US PS) form, and decode-time will raise an error if it
is on the (HI LO nil) form that lyskom-subtract-one-day previously
returned.

Tweak debian devbuilds

See merge request lyskom-elisp-client/lyskom-elisp-client!3

* lyskom-rest.el (lyskom-format-image): Link to jskom when an
  image cannot be displayed.
* swedish-strings.el, english-strings.el (image-no-show): Now
  takes two additional arguments (two links to display).

In emacs-26 duplicate &optional is an error.

  lyskom.el:42124:26:Error: Duplicate &optional
  make: *** [Makefile:195: lyskom.elc] Error 1

The debian source format i specified three years ago doesn't permit
version suffixes (at least now).

The function generates a warning in emacs-25

 lyskom.el:31094:6:Warning: ‘nil’ is not a condition name (in condition-case)

Since it's not used, just remove it instead of trying to fix it.

Don't redefine kbd if existing definition is correct.

Terminate keep-alive in kill-buffer-hook

Since lyskom-keep-alive-timers is a buffer-local variable,
lyskom-keep-alive-callback can't stop the keep-alive timer
if the buffer has been killed.  As a result, it keeps saying ERROR! in
the mini buffer.

On an idea from Christer Ekholm, terminate the timer explicitly with a
kill-buffer-hook instead.  The error logging in
lyskom-keep-alive-callback has been improved too, to provide more
information on what went wrong if there are other error situations in
the future.

To avoid failure when copying the write-protected files.

If HEAD is not a tagged commit then construct lyskom-clientversion the
same way as wen building default target (lyskom.elc)

Commit 8ae3ab53 removed target fast. But I forgot to also remove the
comment telling about it.

Also chmod 444 some more generated files. The reason to write-protect
generated files is to make it harder to accidentally edit them by
mistake.

There is no need to. And if it's writable we don't need to have rm -f
too.

By removing "$(MAKE) $(VERSION-EL)" from the recipe for lyskom.el, and
adding the elisp source-files as dependencies for version.el

make fast doesn't work any more. So instead of trying to fix it, just
remove it.

dont-compile is marked as obsolete in emacs-24.4, and gives a lot of
warnings "Warning: `dont-compile' is an obsolete macro (as of 24.4)."

* lyskom-rest.el (lyskom-do-format): Don't (set-buffer lyskom-buffer)
unless kom-deferred-printing is t. It's not needed then, and
kom-edit-show-commented sets it to nil when inserting the commented
text in *Commented*

Bug introduced in a4b10328.

* elib-string.el (string-replace-match): Track the renamed variables
  elib-string and elib-newtext.
  (elib-string-expand-newtext): Fixed the documentation now that the
    variables are renamed.

The code is supposed to use set-face-strikethru-p if available (in
xemacs). But the function was misspelled in the test, thus never used.

Moved selection of wday from convdate to a more natural place, and
reduced line-length.
