What I could find was:
- In downloads dpi, having to set C locale in the environment before
  exec()ing wget in order to parse the log correctly.

- Dillo resetting to C locale for gtk cmdline option parsing.

- Temporarily resetting LC_NUMERIC to C locale for prefs parsing.
  I don't believe LC_NUMERIC is currently set in the fltk-1.3 era, although
  it might be good to reset in general because of the strtod() in
  Html_parse_length_or_multi_length().
