(bug 14901) Expand release notes
The bug has not been fixed completely and it deserves some space.
Expanded the release notes pseudo-quoting bsitu's comment on the
commit/https://bugzilla.wikimedia.org/show_bug.cgi?id=14901#c63.
The release note mentions most of the terms used by both technical
and non technical users so that they uphold each other and ease
grepping or search (except for case and hyphens):
'(Email)? notifications?', 'Enotif'.
Per Siebrand, it was impossible to both avoid inconsistent wrapping
and respect line length limits, so I've rewrapped the other offenders.
