Description of problem:
Attempting to make fig2dev direct output to a filename with a space or semicolon
with PNG or GIF format fails.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. Create a simple fig file with xfig, say "foo.fig".
2. fig2dev -L gif foo.fig foo\ bar.gif
3. fig2dev -L png foo.fig foo\ bar.png


Actual Results:  For step 2:

[bac@ancora tmp]$ fig2dev -L gif foo.fig foo\ bar.gif
fig2dev: error while converting image.
Command used:
  (ppmquant 256 /tmp/f2d30854.ppm | ppmtogif > foo bar.gif) 2> /tmp/f2d30854.err
Messages resulting:
  ppmtogif: bar.gif - No such file or directory
  ppmquant: making histogram...
  ppmquant: 2 colors found
  ppmquant: choosing 256 colors...
  ppmquant: mapping image to new colors...

Empty output file and empty 'foo' file are produced.

For step 3:

[bac@ancora tmp]$ fig2dev -L png foo.fig foo\ bar.png
Error: /undefinedfilename in (bar.png)

Error in ghostcript command
command was: gs -q -dSAFER -sDEVICE=png16m -r80 -g259x259 -sOutputFile=foo bar.png -

Empty output file produced.

[Both steps work is the space is omitted; both fail in similar ways
with a semicolon, except that output may be found in the file 'foo'.]

Expected Results:  The output files should be successfully created.

Additional info:

This appears to be a shell quoting bug of some sort.
