Glyph to byte offset mapping is now using the line character index (refs #5)
* This works reasonably well unless lines are exceedingly long
(as on a line we always count characters).
The following test case is still slow (on Unicode buffers):
10000<@I/XX/> <%a-1:J;>
While the following is now also fast:
10000<@I/X^J/> <%a-1:J;>
* Commands with relative character offsets (C, R, A, D) have
a special optimization where they always count characters beginning
at dot, as long as the argument is now exceedingly large.
This means they are fast even on exceedingly long lines.
* The remaining commands (search, EC/EG, Xq) now accept glyph indexes.
