Subject: Submodules: Add 'on-demand' value for the 'fetchRecurseSubmodule' option
X-Git-Tag: v1.7.5-rc1~5^2~3
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=bf42b384058ee2b34f587426d0788353ffa9012a;p=git.git

Submodules: Add 'on-demand' value for the 'fetchRecurseSubmodule' option

Now the behavior of fetch and pull can be configured to the recently added
'on-demand' mode separately for each submodule too.
