Update to 4.3.38 from Min Sik Kim in PR pkg/24101.

Changes since 4.3.35:

* Fixed bug 131059. Fix to allow the thousands separator to be used
  correctly with the creation of the initial constant values in the
  Russian locale.
* Fixed bug 130078. Changed the y^x button label to x^y (really x
  superscript y). Adjusted the tooltip message to "Raise displayed
  value to the power of y".
* Fixed bug 130282 again. Needed to remove the "|| tsep[0] == '\0'" check
  from the get_tsep() routine in order to get the thousands separator to
  correctly work in all locales. Note that there is no thousands separator
  now for the C locale.
