errno-error definition vs. documentation

[Andreas Voegele <voegelas@gmx.net>]

Hi,

there's a mismatch between the definition and the documentation of
errno-error.  It seems that the "msg" argument is missing from the
documentation.

scsh/scsh-condition.scm:

 (define (errno-error errno msg syscall . stuff)
   (apply signal 'syscall-error errno msg syscall stuff))

doc/scsh-manual/syscalls.tex:

 \begin{dfndesc}
     {errno-error}{errno syscall .\ data}{\noreturn}{procedure}
