Moved win short directory conversion into bash

[TylerJewell]

Two sets of changes:

1. Moved CHE_HOME short directory conversion of windows from che.bat into che.sh. Thanks @SamHasler.
2. Convert JAVA_HOME to short directory if on Windows.

@garagatyi @eivantsov wdyt?

That will fail if the che.sh isn't invoked from the directory it is in.

Try this:

echo `(cd "$( dirname "${BASH_SOURCE[0]}" )" && cmd //C 'FOR %i in (..) do @echo %~Si')`

The %~dp0 variable only works in the context of a batch script. By invoking cmd and passing it as a command there is no script name or %0 parameter set. So %i ends up as %~dp0\..\... I'm not sure how but %~Si is then geting evaluated to the short name directory of the dir below the current directory.

e.g.:

echo `(cmd //C 'echo %0')`
echo `(cmd //C 'FOR %i in (%~dp0\..\..) do @echo %i')`
echo `(cmd //C 'FOR %i in (%~dp0\..\..) do @echo %~Si')`
echo `(cd "$( dirname "${BASH_SOURCE[0]}" )" && cmd //C 'FOR %i in (..) do @echo %~Si')`

invoked from "C:\VERY LONG\PATH\WITH SUBDIR" using ./testscript.sh outputs:

%0         
%~dp0\..\..
C:\VERY~1\PATH~1\
C:\VERY~1\PATH~1\

invoked from "C:\Some\Other\Dir" using "/c/very long/path/with subdir/testscript.sh" outputs:

%0         
%~dp0\..\..
C:\SOME~1\OTHER~1\
C:\VERY~1\PATH~1\

Yep - good catch. I thought our tests caught that scenario, but it didn't.
BTW, we convert JAVA_HOME now to its short path using the cycgpath utility that you pointed out. Didn't know that existed. Would have saved me 4 hours the first time I tried to solve this :-/

Glad I could help.
