[Nano-devel] quick update, bug reports

[David Lawrence Ramsey]

Barring any major bugs introduced by this patch, this is the
last set of changes I'm making to it (it's massive enough as
it is).

Changes:

* removed junk2.txt from the patch; that was left over from
testing
* fixed a few typos
* removed an unneeded blank line
* added support for the PageUp/PageDown escape sequences (as
opposed to just the ncurses-defined keys, which are already
supported there) to do_help()

I've also found two minor bugs in nano-1.1.9-cvs vanilla
that I haven't been able to fix so far:

Bug #1:
- "export/setenv TERM=ansi" in an xterm from XFree86 4.1.0,
an rxvt 2.6.4, and an aterm 0.4.2, and run pico/nano
- pico 4.2 appears to have no problems in any of these
- in xterm with nano 1.1.9-cvs, the PgUp/PgDn keys will work
in the edit window but not the help window* (^Y/^V will
still work there, though); in rxvt/aterm, massive screen
corruption occurs

* the last item in my patch fixes this

Bug #2:
- type "this is a regexp test" in a blank buffer in nano
- move the cursor to the space between "a" and "regexp"
- do a regular expression search for "^r"
- the "r" in "regexp" will be the only instance found, even
though it isn't at the beginning of the line
- this is probably due to nano's imitation of pico's
behavior where the first match of an expression is found
last when the cursor is at the beginning of it (i. e. the
character just after the cursor is treated as the beginning
of the line and hence is where the search begins)
