Maybe I'm just odd, but most of my coding is done in FTE (http://fte.sourceforge.net/). It's fast, lenient, textmode, and offers just about everything I need -- which, admittedly, isn't much. Some decent syntax-highlighting (still with errors, it especially likes to munge HERE docs), CVS integration, and just the "feeling" I like.
Of course, I may be influenced by my strong liking of the Turbo Pascal 6 / Borland Pascal 7 IDEs.

If FTE is not avaiable, mcedit does a nice job for quick editing of small scripts as well (though it breaks apart completely if you have more than one or two sourcefiles).

vim, emacs, etc. are nice editors, though I never really need all their power.
