On Windows, when PDF is opened with Acrobat Reader, one gets following output:
! I can't write on file `document.pdf'.
Please type another file name for output:
If one simply presses "Enter" to continue, the file `.pdf` is generated. Since this is a common case and `.pdf` is never used as full file name, this file should be ignored, too.
When we use 'thmtools' package for creating 'List of Theorems', auxiliary file '.loe' is created, just as '.toc' for 'Table of Contents' and '.lof' for 'List of Figures'.
A precompiled header(`latex -ini`) compiled creates a `.fmt` file.
To speed up xypic's drawing, precompiled matrices are created with the `\CompileMatrices` entry in the preamble. This creates `*.xyc` files.
endfloat.sty produces these two auxiliary files.
From Section 3.2 of its documentation:
> Loading it will have LTEX produce two extra files with .ttt and .fff extensions (for tables and figures, respectively).
When using TikZ & PGF with:
`\usepackage{tikz} \usetikzlibrary{external} \tikzexternalize`
It creates .dpth and .md5 files for the externalized tikzpictures.
When using minitoc package, LateX often generates multiple .mtc files such as `*.mtc0`, `*.mtc1`, ..., `*.mtc13`, ... This patch allows one to ignore all *.mtc files from index 0 to index 99 (ignoring `*.mtc[1-9][0-9]`).
When doing \usepackage[backref]{hyperref} the pages of the references are shown in the bibliography.
Those files can be safely ignored.

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.
Sometimes it happens that you'd like to commit during a long LaTeX run. During this run, the document.synctex.gz is renamed to document.synctex.gz(busy). And you don't want to commit this file.
