I got what you mean. I removed changes in pgevent.c except for the default
name. I attached the revised patch.

Sorry, but I'm probably not understanding your comment. This may be due to
my English capability. -e is effective only on Windows, so it is placed in
section "Options for Windows". And I could not find a section named "Common
options". -e is currently meangful only with register mode, so it is placed
at register mode in Synopsis section. For example, -D is not attached to
kill mode.
Do you suggest that -e should be attached to all modes in Synopsis section,
or -e should be placed in the section "Options" instead of "Options for
Windows"?
