gitweb: Simplify (and fix) chop_str

warthog9 · gitster · commit 57017b3e1554 · 2010-02-03T17:14:00.000-08:00
The chop_str subroutine is meant to be used on strings (such as commit description / title) *before* HTML escaping, which means before applying esc_html or equivalent. Therefore get rid of the failed attempt to always remove full HTML entities (like e.g. &amp; or &nbsp;). It is not necessary (HTML entities gets added later), and it can cause chop_str to chop a string incorrectly. Specifically: API & protocol: support option to force written data immediately to disk from http://git.kernel.org/?p=daemon/distsrv/chunkd.git;a=commit;h=3b02f749df2cb1288f345a689d85e7061f507e54 The short version of the title gets chopped to API ... where it should be API & protocol: support option to force written data...
