Bug#624245: annoying error message in non-C locale

["Barak A. Pearlmutter" <barak@cs.nuim.ie>]

Package: texinfo
Version: 4.13a.dfsg.1-6

The /usr/bin/texi2dvi shell script invokes
  ... | $EGREP '[A-z]' >&6 || ...
on line 1713.  Unless LC_ALL=C, this gives an error.

  $ echo A:/foo/bar | env LC_ALL=C egrep '^(/|[A-z]:/)' || echo error
  A:/foo/bar

  $ echo A:/foo/bar | env LC_ALL=  egrep '^(/|[A-z]:/)' || echo error
  egrep: Invalid range end
  error

There are a few ways to fix this.  The invocation could be changed to

  ... | env LC_ALL=C $EGREP '^(/|[A-z]:/)' ...

assuming it really is desired to match any of the following

  ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxyz

as in the current code.

Assuming the intent is to match only ASCII alphabetic characters, the
invocation should be

  ... | $EGREP '^(/|[A-Za-z]:/)' ...

or

  ... | env LC_ALL=C $EGREP '^(/|[[:alpha:]]:/)' ...

Assuming the intent is to match alphabetic characters in the current
locale, the invocation should be

  ... | $EGREP '^(/|[[:alpha:]]:/)' ...

or, better,

  ... | $EGREP '^([[:alpha:]]:|)/' ...

Cheers,
