;; Todo:
|
||
|
||
;; - Find/use/create _MTN/log if there's a _MTN directory.
|
||
;; - Find/use/create ++log.* if there's an {arch} directory.
|
||
;; - Use an open *VC-Log* or *cvs-commit* buffer if it's related to the
|
||
;; source file.
|
||
;; - Don't add TAB indents (and username?) if inserting entries in those
|
||
;; special places.
