This fixes "(portability) scanf without field width limits can crash with
huge input data on some versions of libc" warning from cppcheck.
We choose 10 as the field width limit as it is the number of characters in
2^31-1, the largest int.
Note that this was a fork of the earlier 1998-05-02 version and didn't
contain the later changes. Therefore we merge the best of both versions.
wmtime had some additional unnecessary dummy variables, so we use the wmmon
version.
Note that wmckgmail and wmtz were identical; this is the version we use.
wmSMPmon differed only with some whitespace.
wmitime differed only with a bugfix (a segfault when -display is given with
no argument), but this will be fixed again in the next commit.
wmsm.app had patched wmgeneral to work with its xpm; instead we patch its
xpm to work with wmgeneral.
