hgweb: raw file mimetype guessing configurable, off by default (BC) (
issue2923)
Before: hgweb made it possible to download file content with a content type
detected from the file extension. It would serve .html files as text/html and
could thus cause XSS vulnerabilities if the web site had any kind of session
authorization and the repository content wasn't fully trusted.
Now: all files default to "application/binary", which all important
browsers will refuse to treat as text/html. See the table here:

# An example hgweb CGI script, edit as necessary
# See also http://mercurial.selenic.com/wiki/PublishingRepositories
# Path to repo or hgweb config to serve (see 'hg help hgweb')
config = "/path/to/repo/or/config"
# Uncomment and adjust if Mercurial is not installed system-wide:
#import sys; sys.path.insert(0, "/path/to/python/lib")
# Uncomment to send python tracebacks to the browser if an error occurs:
#import cgitb; cgitb.enable()
