Subject: Abstract out CVS's involvement in the wrapper:
X-Git-Tag: 3.14159265~74^2~2
X-Git-Url: http://git.vanrenterghem.biz/git.ikiwiki.info.git/commitdiff_plain/aafd267ee099ddb8ff4129a0e4d46964be866f6d

Abstract out CVS's involvement in the wrapper:

* In Wrapper.pm, add a new hook "wrapperargcheck" to examine argc/argv
  and return success or failure. In the failure case, the wrapper
  terminates.

* In cvs.pm, implement the new hook to return failure if a directory is
  being cvs added.
