GIT:
GIT: This is my first patch. `https://www.gnu.org/software/automake/' mentions
GIT: `The HACKING file present in the Automake git repository should explain
GIT: how to properly prepare, format and post a patch.'. However,
GIT: the HACKING file does not mention `git format-patch'. Should I add it?
GIT:
GIT: This patch add autoreconf, autogen and perl as supported programs to
GIT: the `missing' script. This is already done to my local copy of
GIT: the `missing' script. It is useful because I need to use
GIT: the `missing' script as wrapper to invoke autoreconf, autogen and perl
GIT: from the `bootstrap' script. Hopefully, this is useful to the others
GIT: as well so I submit this patch.
GIT:
GIT: Feel free to discuss the above, accept/reject patch and reply to
GIT: this email. This patch can be apply by `git am *.patch' (tested).

Subject: [PATCH] missing: add autoreconf, autogen and perl as supported
 programs

autoreconf, autogen and perl are added as supported programs
since they are commonly used with the autotools.
Some rewriting is done but the logic should NOT change.

`GNU programs' is changed to `GNU programs and friends'
since flex and perl are not part of GNU.
