Bug#342781: tex-common: postinst fails when shell is /bin/ksh

[Robert Luberda <robert@debian.org>]

Package: tex-common
Version: 0.12
Severity: normal
Tags: patch

Hi,
when /bin/sh points to pdksh, postinst fails with the error:
	An essential entry is wrong in /etc/texmf/texmf.d/55Fonts.cnf:
	TEXFONTMAPS does not contain
	{fonts/map,}/{$progname,pdftex,dvips,}//

However, the file contains the above entry. The problem is caused by the
ksh's brace expansion mechanism causing the following line to fail:
    if ! echo $line | grep -q '{fonts/map,}/{\$progname,pdftex,dvips,}//';

The $line is not quoted causing ksh to expand the expression in braces:

[141]/home/robert> echo $SHELL                                      
/bin/ksh
[142]/home/robert> line='{fonts/map,}/{$progname,pdftex,dvips,}//' 
[143]/home/robert> echo $line
fonts/map/$progname// fonts/map/pdftex// fonts/map/dvips// fonts/map///
/$progname// /pdftex// /dvips// ///


Attached patch fixes the problem.


Best Regards
robert
