[squid-dev] [PATCH] chop() should always clear empty buffers

[Alex Rousskov]

Hello,

    Triage of another trunk bug (see the next email) led me to a problem
in SBuf::chop() that the attached patch attempts to address.

The old chop() code was trying to make the clearance decision ASAP,
without normalizing parameters first and missed most clearance cases as
the result.


HTH,

Alex.
