zgrep does not correctly pass short options to grep

[Chris Adams]

zgrep --help / man zgrep say that “OPTIONs are the same as for 'grep'.” and “All options specified are passed directly to grep.”, respectively. Testing shows that this does not work with the -h option:

-h, --no-filename
              Suppress the prefixing of file names on output. This is the default when there is only one file (or
              only standard input) to search.

Looks like a regression in Precise: it was fine in Lucid. The line in question is 141 of zgrep.in, which only got the "-h" option added post gzip 1.4 (commit cc1c692e4cf115ece8391aaa5f45041065a0c64a, sSep 15th 2010).

Lucid has 1.3.12 of gzip, but gzip_1.3.12-9ubuntu1.1.diff patches zgrep to add -h to line 108 of zgrep.in.

Looks like that needs to be added as a patch in the Precise build (patch attached; just add to debian/patches dir and reference in "debian/patches/series")

NB: Until this makes it into a package, "--no-filename" will have the equivalent effect.

The attachment "Patch to zgrep.in" seems to be a patch. If it isn't, please remove the "patch" flag from the attachment, remove the "patch" tag, and if you are a member of the ~ubuntu-reviewers, unsubscribe the team.

The -h option works in Saucy, which will become Ubuntu 13.10, so I am marking this bug as Fix Released and have opened a task for Precise.

[Steve Langasek (vorlon)]

The Precise Pangolin has reached end of life, so this bug will not be fixed for that release
