bug#34148: 25.2; cal-tex.el: missing blank between month and day in latex rendered output

[andre]

There is a bug in the function cal-tex-cursor-week-iso of cal-tex.el
file. It will generate a LaTex output of the requested week, but in the
rendered PDF there is no space between the months name and the day.

Reason for this is that a single space character is used but which is
not recognized by LaTeX because it is not in between to text characters.

So the line 909 is:
        (insert " ")
but it shall be
        (insert "\\ ")

This but may also be in other parts of the same file.

regards
André

Thanks, I fixed this and another occurrence of the same issue on the
emacs-26 branch.
