Yes, you are right.

I suggested to remove cz[sk]hyph.tex because I have tried to solve the
second problem of cz/sk hyphen patterns: its duplicity in two files
cz[sk]hyphen.tex versus cz[sk]hyph.tex.

The cz[sk]hyphen.tex can't be removed because the csplain is frozen
with all names of used files. There exist many home-made macros which
uses this names.

The solution of this duplicity can be following: leave cz[sk]hyph.tex
files in babel system with only one line inside:

\input czhyphen    or   \input skhyphen .

I don't see the better solution of this problem if you persists on the
short names in babel system. I persist on long names in csplain :-).

Warning: don't replace the cz[sk]hyph.tex files by these one-line
alternatives immediatelly! If you do it, the error in babelised latex
occurs. I will release the new csplain.tar with the corrected
cz[sk]hyphen.tex files which will accept the babelised formats (plain
and latex). You can change cz[sk]hyph.tex files _after_ the new
release of csplain.tar will be included into teTeX. I will plan the
new release during one-two weeks and I will report to Thomas Esser
about it.

Oops, I leave these files in my csplain.tar. This is my mistake.
Remove these files (can be done immediatelly). The enctex is only
an optional package, not required by CSTeX. If there exists another way
of re-encoding on TeX input preprocessor level (--transalte-file
option in web2c based TeX distributions, for example), you need not
enctex. I will remove these files in the new release of csplain.tar.

Yes. The actual problem with czhyph.tex is the next example of the
unstability of the babel.
