gitweb: Teach "a=blob" action to be more lenient about blob/file mime type

jnareb · gitster · commit dfa7c7d221d0 · 2007-12-16T11:56:26.000-08:00
Since 930cf7d 'blob' action knows the file type; if the file type is not "text/*" or one of common network image formats/mimetypes (gif, png, jpeg) then the action "blob" defaulted to "blob_plain". This caused the problem if mimetypes file was not well suited for web, for example returning "application/x-sh" for "*.sh" shell scripts, instead of "text/plain" (or other "text/*"). Now "blob" action defaults to "blob_plain" ('raw' view) only if file is of type which is neither "text/*" nor "image/{gif,png,jpeg}" AND it is binary file. Otherwise it assumes that it can be displayed either in <img> tag ("image/*" mimetype), or can be displayed line by line (otherwise).
