* groffer.sh: new mode `pdf'
- PDF (Portable Document Format):
  -> Transform groff `ps' output into pdf using `gs'.
  -> Pro: PDF viewers provide text searching (!).
  -> Con: the transformation is quite slow.
  -> Not suitable as an auto mode.
- New options `--pdf', `--pdf-viewer', `--mode pdf'.
- Standard pdf viewers `xpdf' and `acroread'.
- For `xpdf', choose zoom `z 3' for 100 dpi, `z 2' for 75 dpi.

* groffer.sh: support bzip2 decompression
- add test for `bzip2' with necessary options
- extend functions `catz()' and `save_stdin()'.

* TODO
remove entry on `bzip' decompression (done).

* groffer.man:
- Document new `pdf' features.
- Document new `bzip2' decompression.
- Fix documentation for `--auto-modes'.

* groffer.sh: minor fixes
- Improve device tests in `tty' and `dvi' modes.
- Internally, map mode `auto' to '' to facilitate tests.
- Fix auto mode sequence to: `ps,x,tty' as was intended.
