I added two options to a text tag, based on the same code as for the -foreground option. This quite small.

tkTextPatch.tgz contains a README, a patch file and an example of use. The patch should be applied from the Tk source directory, because it will patch doc/text.n and generic/tkText* files.

the default behavior of -underline and -overstrike options of a text tag is to draw a line with the same color as the tagged text (or default color if there is no specific foreground). I defined two new options -underlinefg and -overstrikefg that define a specific color for the underline or the overstrike line. If these options are not set, or set to "{}", then the behavior is the same as the standard one, ie, the text color is used instead
I had already defined this enhancement for Tk3.6 and sent a patch (in 1994?) , but we did the move to Tk8.0 only last year.

Note: a subtlety here is that it seems as if the OS may draw
the underline under some circumstances, and Tk under other
circumstances.  This means the patch would actually need to
make sure the OS _didn't_ draw the underline for it to have
control over colour.

Looks like a good idea, but needs a TIP.  Perhaps the author
can be persuaded to update the patch for CVS head and submit
a TIP.
