`bandit -rf custom` only shows up to 3 warnings

[bgrant]

Describe the bug
Running bandit with -rf custom seems to output a maximum of three warnings (no matter how many there are).

To Reproduce
Steps to reproduce the behavior:

1. Clone bandit
2. Run bandit -rf custom examples (on the provided examples directory)

Output

$ bandit -rf custom examples                                                                                                                                                   <<<

/Users/robert.grant/projects/bandit/examples/cipher-modes.py:6: B305[bandit]: MEDIUM: Use of insecure cipher mode cryptography.hazmat.primitives.ciphers.modes.ECB.

Expected behavior
I would expect to see all security errors identified, in a one-per-line format.

Bandit version

bandit 1.5.1
  python version = 3.6.8 (default, Feb 12 2019, 17:27:09) [GCC 4.2.1 Compatible Apple LLVM 10.0.0 (clang-1000.10.44.4)]

Additional context
I use the examples folder here, which seems to contain bad files on purpose (generates the ERROR above). I see the same behavior on another directory without bad files.

Thanks!

It looks like this was fixed as a side effect of #380 (the actual issue seems to be due to @ericwb's comment). Not sure what your release schedule looks like, but this particular fix looks like it missed the 1.5.1 release by a few days. Any thoughts on when this might be released?
