Details:

I'm working with the current dev version as of last week, and uninstalled my
statistics package (for a different error). Then I wanted to reinstall it but
all I get is a parse error in linkage.m:


>> pkg install -forge statistics
warning: doc_cache_create: unusable help text found in file 'gmdistribution'
warning: called from
    doc_cache_create>handle_function at line 91 column 5

Some additional info on this
* this line in linkage.m also exists in a couple of previous versions of
statistics
* I also can't install any of the previous statistics versions
* I do have an octaverc-file to load at startup but the statistics package is
not in that file
* I also tried this on a Linux machine with the current dev version, only the
io package installed and no octaverc-file - leads to the same error
* I have access to Octave 5.1 running on a Windows 10 machine - I can install
the package on there with no error message (checked with statistics-1.4.0 and
statistics-1.4.1)
* with Octave 5.1, 'test linkage' leads to 12 out of 12 passed tests, so the
parser can clearly interpret that line after all
