If the value of VAR is not numeric, the first time you add one to VAR the variable will be set to 1 (non numeric value is trated as zero).

NAME
git-var - Show a Git logical variable SYNOPSIS
git var ( -l | <variable> ) DESCRIPTION
Prints a Git logical variable. OPTIONS
-l Cause the logical variables to be listed. In addition, all the variables of the Git configuration file .git/config are listed as well. (However, the configuration variables listing functionality is deprecated in favor of git config -l.) EXAMPLE
$ git var GIT_AUTHOR_IDENT Eric W. Biederman <ebiederm@lnxi.com> 1121223278 -0600 VARIABLES
GIT_AUTHOR_IDENT The author of a piece of code. GIT_COMMITTER_IDENT The person who put a piece of code into Git. GIT_EDITOR Text editor for use by Git commands. The value is meant to be interpreted by the shell when it is used. Examples: ~/bin/vi, $SOME_ENVIRONMENT_VARIABLE, "C:Program FilesVimgvim.exe" --nofork. The order of preference is the $GIT_EDITOR environment variable, then core.editor configuration, then $VISUAL, then $EDITOR, and then the default chosen at compile time, which is usually vi. GIT_PAGER Text viewer for use by Git commands (e.g., less). The value is meant to be interpreted by the shell. The order of preference is the $GIT_PAGER environment variable, then core.pager configuration, then $PAGER, and then the default chosen at compile time (usually less). SEE ALSO
git-commit-tree(1) git-tag(1) git-config(1) GIT
Part of the git(1) suite Git 1.8.3.1 06/10/2014 GIT-VAR(1)
