Sat Jul 6 05:43:41 1991 Per Cederqvist (ceder at lysator)
* Fullbordade {ndringen fr}n char till unsigned char i
s-string.[hc] som Peter p}b|rjade.
* Skrev om Makefilen f|r att klara RCS.
* Alla filer i libmisc.a placerade under RCS.
* s-collat-tables.[hco] omd|pt till s-collat-tabs.[hco]. ar tycker
inte om f|r l}nga namn.
Thu Dec 20 04:59:36 1990 Thomas Bellman (bellman at lave)
* s-string.[ch]: s_strchr() och s_strrchr(): Lade till en
parameter som anger var s|kningen ska b|rja.
* s-string.c: [ndrat fr}n if-satser f|r kontroll av parametrar
till att anv{nda assert()-makrot.
* s-string.[ch]: Lade till s_strrchr().
* zmalloc.c: Fixat en del buggar d{r pekare till z_info-structen
returnerades i st f pekare efter denna, samt lite annat.
Sat Dec 8 03:05:51 1990 Thomas Bellman (bellman at laila)
* [ndrade tillbaka s_strcpy(). Den ska sl{ppa loss minnet {ven om
den f}r en EMPTY_STRING.
Sat Dec 1 12:09:35 1990 Lars Willf|r (willfor at nanny)
* [ndrade s_strcpy s} att den med s{kerhet fungerar {ven om
source_string == EMPTY_STRING.
