[texdoc] texdoc support for zipped files

Hi Norbert, hi Frank,

first of all, sorry for my late reply.

Ok, that was easily fixed.

Right, I applied your patch for this part, thanks for providing it.

I tried a somehow easier solution by changing the function that quotes the
filename.

Right, my workaround has the same limitation. I don't think it's a big problem,
since most viewer commands should accept options first and filename at end (that
is, xpdf -option %s. I've added a comment in texdoc.cnf documenting this limitation.

I manually applied the first part of your patch to texdoc's trunk, and tried
another approach for the quoting problem. Now, taking svn r59 and just changing
support-zipped to true (line 104) should work:

mpg at roth:~% PDFVIEWER='(xpdf %s) &' texdoc -v4 foobar                     12:18
texdoc debug1: /home/mpg/bin/texdoc version 0.42+ svn r59

lost+found  wpa_ctrl_2712-1
mpg at roth:~%

The only remaining quirk is the spurious info message "trying full search mode".
But since I intend to rework the way texdoc matches filenames soon, I'll
probably leave it alone for now.

Please test and report any problems. If everything is ok for you, I'll probably
release the fixed version as 0.43 in TL, so that you can take the version from
TL svn, not texdoc svn.
