Yes, if you always use \mymacro in this way:

    \def\mymacro#1\par{ ... }

will get rid of the \par. It will still insert an extra space (from
the first newline character) though. If you want to get rid of that one
as well, insert a space between "#1" and "\par".
If you sometimes use \mymacro differently, things get a lot harder.
You could do something like temporarily changing the definition of \par,
or you could use \futurelet to check if a \par is coming next. I don't
want to go into that now.

Why not? No editor? No compiler so that you can write a trivial
filter? No computer? ... (just curious)
