Revision 1.4, Sun Feb 27 00:22:08 2005 UTC (19 years, 3 months ago) by jfb
Branch: MAIN
Changes since 1.3: +2 -2 lines
Many improvements to the RCS support:
- make it possible to specify creation and the file mode
in rcs_open()
- implicitly write the contents to disk on rcs_close() if the
RCS handle has been changed
- fix a bug in the output of the `expand' keyword
- add functions to retrieve and modify the expansion mode
- rcs_parse() shouldn't be available to the outside
- empty string instead of `(null)' if there is no description
ok Joris
