[Bug Report] git log -L:<funcname>:<file>

[Weishi Zeng <amwish.zeng@gmail.com>]

Summary:
git log -L:<funcname>:<file>
would fail if there's any java-style comment that appears before the
<funcname> string in the file.


Details:
Thank you for filling out a Git bug report!
Please answer the following questions to help us understand your issue.

What did you do before the bug happened? (Steps to reproduce your issue)
git log -L:'myFunction':~/a.java
The file is a java file that contains comment before the function name.
E.g.
/**
* comments will interrupt the regex match
*/
private static void myFunction() {}

What did you expect to happen? (Expected behavior)
As described, it should return me the commit history that touched this function

What happened instead? (Actual behavior)
It returns error:
fatal: -L parameter 'myFunction' starting at line 1: no match

Anything else you want to add:
If the function name string to search for appears before any
java-style comment, it returns a valid response.
