Git v1.8.0.1 Release Notes
==========================

Fixes since v1.8.0
------------------

 * The configuration parser had an unnecessary hardcoded limit on
   variable names that was not checked consistently.

 * The "say" function in the test scaffolding incorrectly allowed
   "echo" to interpret "\a" as if it were a C-string asking for a
   BEL output.

 * "git mergetool" feeds /dev/null as a common ancestor when dealing
   with an add/add conflict, but p4merge backend cannot handle
   it. Work it around by passing a temporary empty file.

 * "git log -F -E --grep='<ere>'" failed to use the given <ere>
   pattern as extended regular expression, and instead looked for the
   string literally.

 * "git grep -e pattern <tree>" asked the attribute system to read
   "<tree>:.gitattributes" file in the working tree, which was
   nonsense.

 * A symbolic ref refs/heads/SYM was not correctly removed with "git
   branch -d SYM"; the command removed the ref pointed by SYM
   instead.

 * Earlier we fixed documentation to hyphenate "remote-tracking branch"
   to clarify that these are not a remote entity, but unhyphenated
   spelling snuck in to a few places since then.

 * "git pull --rebase" run while the HEAD is detached tried to find
   the upstream branch of the detached HEAD (which by definition
   does not exist) and emitted unnecessary error messages.

 * The refs/replace hierarchy was not mentioned in the
   repository-layout docs.

 * Sometimes curl_multi_timeout() function suggested a wrong timeout
   value when there is no file descriptors to wait on and the http
   transport ended up sleeping for minutes in select(2) system call.
   A workaround has been added for this.

 * Various rfc2047 quoting issues around a non-ASCII name on the
   From: line in the output from format-patch have been corrected.

 * "git diff -G<pattern>" did not honor textconv filter when looking
   for changes.

 * Bash completion script (in contrib/) did not correctly complete a
   lazy "git checkout $name_of_remote_tracking_branch_that_is_unique"
   command line.

 * RSS feed from "gitweb" had a xss hole in its title output.

 * "git config --path $key" segfaulted on "[section] key" (a boolean
   "true" spelled without "=", not "[section] key = true").

 * "git checkout -b foo" while on an unborn branch did not say
   "Switched to a new branch 'foo'" like other cases.

Also contains other minor fixes and documentation updates.
