You should be careful.  Your language.dat files might be overwritten
when you update your system.  I don't know whether MiKTeX concatenates
language.dat files found in various directories.  If you are using TeX
Live, it's best to put your own hyphenation into a file called
"language-local.dat".  This will not be overwritten.  Run

  tlmgr --help

for more information.

In TeX Live, texhash and mktexlsr is one and the same script.  The
latter exists for consistency (there are other mktex... scripts) and
the name "texhash" is easier to remember.  However, the point is that
it's required to re-generate the format files, otherwise changes to
language.dat have no effect.  Hyphenation patterns are part of the
format file.  Only LuaTeX is loading hyphenation patterns at run-time.

I don't know what the --dump option means but since you said that it
works for you, it probably invokes fmtutil in order to re-create the
format files.  I suppose that the reason it didn't work for Krzysztof
is that the format files had not been re-created.  On TeX Live

  mktexlsr 
  fmtutil --all

This should work but I strongly recommend to create a file
"language-local.dat" for personal hyphenation patterns and follow the
instructions of

  tlmgr --help

  Reinhard
