Bug#965090: singular-ui-emacs: Wrong option name in error message

[Volker Diels-Grabsch]

Package: singular-ui-emacs
Version: 1:4.1.1-p2+ds-3
Severity: minor

Dear Maintainer,

When running ESingular and its Emacs load file is missing, the
following error message occurs:

Error: Can't find emacs load file for Singular mode.
 Expected it at /usr/bin/../share/singular/emacs/.emacs-singular
 Specify with --emacs_load option,
 or set ESINGULAR_EMACS_LOAD environment variable,
 or put file '.emacs-singular' in your home directory.
Use `ESingular --help' for a complete list of options

This error message mentions the option "--emacs_load", which
doesn't exist.  It is neamed "--emacs-load" instead.

It would be great if this error message was fixed.

As a side node, it wouldn't harm to run "realpath" over the
directory name, so that the error message points to
"/usr/share/singular/emacs/" rather than
"/usr/bin/../share/singular/emacs/".


Regards,
Volker
