Commit message is truncated when a period is included

Summary

When a commit is pushed to a remote repo, if the commit contains a period, the text after the period is truncated.

Steps to Reproduce

1. Create a repo in Bitbucket Server
2. Clone the repo locally
3. Create 2 files (in this example a README and .gitattributes)
4. Git add the 2 files
5. Git commit the files with the following example git commit message:

   git commit -m $'A. Summary line should be displayed\n\nFurther details are not so important'
   

6. Check the commit on the command line:

   [nhansberry:~/dev/stash_repos/truncate] master ± git show --pretty=fuller
   commit f13762b047303af8bfe3ea018e4df82787dc73e7 (HEAD -> master)
   Author:     Nathaniel Hansberry <nhansberry@atlassian.com>
   AuthorDate: Mon Mar 26 11:15:07 2018 -0500
   Commit:     Nathaniel Hansberry <nhansberry@atlassian.com>
   CommitDate: Mon Mar 26 11:15:07 2018 -0500
   
       A. Summary line should be displayed
       
       Further details are not so important
   
   diff --git a/.gitattributes b/.gitattributes
   new file mode 100644
   index 0000000..e69de29
   diff --git a/README b/README
   new file mode 100644
   index 0000000..e69de29
   

7. Git push and check the commit message in the UI

Expected Results

• We should see the entire commit message

Actual Results

• Everything after the period is truncated
  

Notes

• If only 1 file is included in the push the message is displayed correctly
