This is to be nicer to people with unusable GECOS field. "git-var -l" is currently broken in that when used by a user who does not have a usable GECOS field and has not corrected it by exporting GIT_COMMITTER_NAME environment variable it dies when it tries to output GIT_COMMITTER_IDENT (same thing for AUTHOR). "git-pull" used "git-var -l" only because it needed to get a configuration variable before "git-repo-config --get" was introduced. Use the latter tool designed exactly for this purpose. "git-sh-setup" used "git-var GIT_AUTHOR_IDENT" without actually wanting to use its value. The only purpose was to cause the command to check and barf if the repository format version recorded in the $GIT_DIR/config file is too new for us to deal with correctly. Instead, use "repo-config --get" on a random property and see if it die()s, and check if the exit status is 128 (comes from die -- missing variable is reported with exit status 1, so we can tell that case apart).
