Reword some parts to sound less redundant.

Make it so that position=0 is still the beginning of the file, even if a BOM exists.
Adding Unicode to the File API made READPOS/WRITEPOS more complicated, but keeping 0 as the beginning of the file is important for backward compatibility because it was documented that way.

Fix wording in a comment

Go back to using \xHHHH instead of \uHHHH to escape non-ASCII characters.
Even though \u has been supported since C++11, the latest i686-w64-mingw32-windres on Cygwin doesn't support it, which corrupted any non-ASCII character in the screen saver's dialog boxes.

To work around the problem that originally made me switch from \x to \u, mklocale.pl now splits the string literal wherever a new \x escape sequence "absorb" subsequent characters that happened to be hexadecimal digits. This results in uglier header files, but the real source code is the .txt files.

Add a missing period.

Fix Bug #534; Make sure the commander input's caret is visible clearing its contents.
This fixes a problem where typing a long line into the commander's input box would scroll right and the first character of the next line typed would be hidden from view.
