svnimport: Convert the svn:ignore property

Put the value of the svn:ignore property in a regular file when
converting a Subversion repository to GIT. The Subversion and GIT
ignore syntaxes are similar enough that it often just works to set the
filename to .gitignore and do nothing else.

DESCRIPTION
@ -65,6 +65,12 @@ When importing incrementally, you might need to edit the .git/svn2git file.
Prepend 'rX: ' to commit messages, where X is the imported
subversion revision.
-I <ignorefile_name>::
Import the svn:ignore directory property to files with this
name in each directory. (The Subversion and GIT ignore
syntaxes are similar enough that using the Subversion patterns
directly with "-I .gitignore" will almost always just work.)
-m::
Attempt to detect merges based on the commit message. This option
will enable default regexes that try to capture the name source
