exewrapper: add .dll to LoadLibrary() argument
LoadLibrary() changes behavior depending on whether the argument
passed to it contains a period. From the MSDN docs:
If no file name extension is specified in the lpFileName parameter,
the default library extension .dll is appended. However, the file name
string can include a trailing point character (.) to indicate that the
module name has no extension. When no path is specified, the function
searches for loaded modules whose base name matches the base name of
the module to be loaded. If the name matches, the load succeeds.
Otherwise, the function searches for the file.
As the subsequent patch will show, some environments on Windows
define their Python library as e.g. "libpython2.7.dll." The existing
code would pass "libpython2.7" into LoadLibrary(). It would assume
"7" was the file extension and look for a "libpython2.dll" to load.
By passing ".dll" into LoadLibrary(), we force it to search for the
exact basename we want, even if it contains a period.

'''removes files not tracked by Mercurial
Delete files not known to Mercurial. This is useful to test local
and uncommitted changes in an otherwise-clean source tree.
This means that purge will delete the following by default:
- Unknown files: files marked with "?" by :hg:`status`
- Empty directories: in fact Mercurial ignores directories unless
they contain files under source control management
But it will leave untouched:
- Modified and unmodified tracked files
- Ignored files (unless --all is specified)
- New files added to the repository (with :hg:`add`)
The --files and --dirs options can be used to direct purge to delete
only files, only directories, or both. If neither option is given,
both will be deleted.
If directories are given on the command line, only files in these
directories are considered.
Be careful with purge, as you could irreversibly delete some files
you forgot to add to the repository. If you only want to print the
list of files that this program would delete, use the --print
option.
