Removed intl/ entirely, and a few more tweaks by gettextize.
- i18nized a few strings used in DEBUG mode. (DLR)
- Some chars being assigned 0 are now assigned '\0'. (DLR)
- Put header files in a more consistent order. (DLR)
- Put header file #includes in a more consistent order. (DLR)
- Remove some unneeded blank lines and spaces, and make some
spacing more consistent. (DLR)
- When possible, use iscntrl() to determine whether a character
is a control character or not. (DLR)
- Miscellaneous typo fixes. (DLR)
- Many fixes to the help browser and shortcut lists: efficiency
updates, consistency fixes, help text fixes and improvements,
and spacing improvements. (David Benbennick)

Make startline an int instead of a long, since it's supposed to

Also, pass current_x_find to strstrwrapper() so we know whether
we're at the beginning of a string or not (see changes to
strstrwrapper() below), and reset it between lines. (DLR)
do_gotoline():
