Renaming markdown files corrupts links with fragments and angle brackets

[gmccullo]

Type: Bug

Create a project with 2 files:

foobarA.md:

# header A

[foobarB: header-1](<foobarB.md#header-1>)

foobarB.md:

# header 1

[foobarA: header-a](<foobarA.md#header-a>)

Rename either file and answer yes to the "Update Markdown links" prompt.

The links in one or both files will be broken. The fragment delimiter ('#') and the left angle ('<') are deleted:

# header A

[foobarB: header-1](foobarB2.mdheader-1>)
