combining numbering rule for eledmac and be less devourer
Merge pull request #1008 from maieul/master

Add rules for TeX packages (e)ledmac and (e)ledpar. References from manuals:

eledmac p. 46:
> Each section will read and write an associated "line-list file", containing information used to do the numbering; the file will be called `<jobname>.nn`, where `nn` is the section number. However, you may direct that an extra string be added before the `nn` in that filename, in order to distinguish these temporary files from others: that string is called `\extensionchars`. Initially it's empty, since different operating systems have greatly varying ideas about what characters are permitted in file names. So `\renewcommand{\extensionchars}{-}` gives temporary files called `<jobname>.-1`, `<jobname>.-2`, etc.

eledmac p. 112:
> Endnotes of all varieties are saved up in a file, typically named `<jobname>.end`.

eledpar p.8:
> The `\beginnumbering` macro resets the line number to zero, reads an auxiliary file called `<jobname>.nn` (where `<jobname>` is the name of the main input file for this job, and `nn` is 1 for the first numbered section, 2 for the second section, and so on), and then creates a new version of this auxiliary file to collect information during this run. Separate auxiliary files are maintained for right hand texts and these are named `<jobname>.nnR`, using the ‘R’ to distinguish them from the left hand and serial (non-parallel) texts.
