Bug#827880: devscripts: [debrelease] [debsign] DEBRELEASE_DEBS_DIR ignored while --debs-dir works

[Carl Suster]

Package: devscripts
Version: 2.16.5
Severity: normal

Dear Maintainer,

Both debrelease and debsign claim in their documentation that the environment
variable DEBRELEASE_DEBS_DIR is equivalent to setting the command line option
--debs-dir, however both scripts seem to ignore the env variable.

    $ DEBRELEASE_DEBS_DIR=../build-area debsign -S
    debsign: Can't find or can't read changes file !
    $ debsign --debs-dir=../build-area -S
    <normal output>

    $ DEBRELEASE_DEBS_DIR=../build-area debrelease -S mentors
    debrelease: could not find/read changes file ../<package>_source.changes!
    $ debrelease --debs-dir=../build-area -S mentors
    <normal output>

As an aside I note that the two scripts report the same error with different
text, and that the message given by debrelease is more helpful in that it
includes the exact filename it's looking for.

Cheers,
Carl
