[tlbuild] On scripts without 'x' permission

[Angelo Graziosi]

I have seen that after a complete installation of TL2009 (on Cygwin) 
there are scripts in texmf/scripts and texmf-dist/scripts which haven't 
'x' permission. For example:

find /usr/local/texlive/2009/texmf/scripts -name "*.pl" | xargs ls --color

shows that

/usr/local/texlive/2009/texmf/scripts/tetex/updmap.pl
/usr/local/texlive/2009/texmf/scripts/tex4ht/htcopy.pl
/usr/local/texlive/2009/texmf/scripts/tex4ht/htmove.pl
[...]

are without 'x' perm.

Instead:

find /usr/local/texlive/2009/texmf-dist/scripts -name "*.pl" | xargs ls 
--color

shows that

/usr/local/texlive/2009/texmf-dist/scripts/context/perl/makempy.pl
/usr/local/texlive/2009/texmf-dist/scripts/context/perl/mptopdf.pl
[...]

are without 'x' too.

Is that to be expected? or we need something like this

find /usr/local/texlive/2009/texmf[-dist]/scripts -name "*.pl" | xargs 
chmod +x

as postinstall actions?


Thanks,
Angelo.
