Search engines that are not markup savvy (including my eyes) find markup
more disruptive than a single character, particularly if it occurs

Note that I have chosen relatively non-intrusive markup. When I edit text
with markup, I want to see both WYSIWYG and exact markup at the same time.
This is not possible, but the single character is less intrusive to the
WYSIWYG model than the markup. On the other hand, seeing
This is a paragraph of text.
isn't that intrusive. In fact, the latter markup hardly hinders
a plain text search engine. Of course, my single character soft hyphen
does hinder my plain text search engine, but at least I am not talking
about an arbitrary distance (e.g. egrep search pattern en?gines will
produce less false positives than en.*gines and does not require me to
know the exact spelling of the markup I am looking for, as the whole
purpose of my search, for example, was to figure out the answer to that
very question. Note that using a WYSIWYG editor would not help me find
that out either.)
