Browse source 
* doc/misc/eglot.texi (Eglot Features): Add comma after @xref.

* msdos/sed2v2.inp (GNULIB_ISSYMLINK): Define to 1.

* msdos/sedlibmk.inp (HAVE_RANDOM_H): Undefine, in line with its
deletion from gnulib.mk.
(GL_GNULIB_STRINGEQ): Define to 1.

* src/msdos.c (careadlinkat): NULL terminate at the end of the
data written, not one character beyond the same.
