obsolete lines in gitlab.rb.template
There is a block with obsolete lines in gitlab.rb.template (Lines 189/190):
# ![Company Logo](http://www.companydomain.com/logo.png)
# [Learn more about CompanyName](http://www.companydomain.com/)'
This block was supposed to be removed in 5c652be7 ('Removed extra_sign_in_text option')
(I just found this while synchronizing my gitlab.rb with this template.)
Edit: the line # gitlab_rails['smtp_port'] = 456
(Line 262) can also be confusing because 456 looks similar to 465. SMTP over SSL often uses TCP Port 465, not 456! (Same in the GitLab CI email server settings section at line 582.)
