Subject: searchmsg: preserve hard tabs, but drop CR (\r)
X-Git-Tag: v1.0.0~631
X-Git-Url: http://www.git.stargrave.org/?a=commitdiff_plain;h=f4af1462c2e52a5f4ed8b7de855868b8d457627e;p=public-inbox.git

searchmsg: preserve hard tabs, but drop CR (\r)

Hard tabs *may* be searchable, so preserve them since they do
not take up any more space than a normal space.  However, CR
(carriage return) is worthless and likely a sign of a buggy mail
(or spam) client anyways.
