[texinfo-1.12] missing PATH=$(util_srcdir) in doc/Makefile.am

[Michael Haubenwallner]

Hi,

there's a minor bug in texinfo (1.12)/doc/Makefile.am in both the
commands for "texi2pdf.1" and "pdftexi2dvi.1".

*) help2man calls >$(util_srcdir)/texi2pdf --help< to get the input for
the manpage to be created.

*) texi2pdf calls >texi2dvi --pdf ${1+"$@"}<, using PATH to find it.

*) When there is some sufficient texi2dvi in PATH, there's no error at
all, but texi2dvi.1 contains the help-output of the already installed
texi2dvi, not the local one from $(util_srcdir).

*) If there is no texi2dvi available in PATH, help2man bails out with
"can't get `--help' info from ../util/texi2pdf" for >texi2pdf.1<, while
it works for >texi2dvi.1<.

Why I encounter this bug: I've slightly modified util/texi2dvi and
util/texi2pdf (use "/usr/bin/env bash" instead of "/bin/sh"), so their
manpages want to be recreated because of newer modification timestamps.

Attached is a proposed patch to have $(util_srcdir) in PATH while
creating doc/texi2pdf.1 and doc/pdftexi2dvi.1.

This is the output of make:
