`(lldb) b` can be used in two different ways:
1. Running `b` without arguments, it lists all existing breakpoints.
2. Running `b` with additional arguments, it adds breakpoints.
However, the help message doesn't mention the first use case. This patch adds
help message to mention it by adding "List all breakpoints, or ...".
**Without patch**:
```
(lldb) help b
Set a breakpoint using one of several shorthand formats. Expects 'raw' input
(see 'help raw-input'.)
Syntax:
_regexp-break <filename>:<linenum>:<colnum>
main.c:12:21 // Break at line 12 and column 21 of main.c
...
(lldb) apropos breakpoint
b -- Set a breakpoint using one of several shorthand
formats.
```
**With patch**:
```
(lldb) help b
List all breakpoints, or set a breakpoint using one of several shorthand
formats. Expects 'raw' input (see 'help raw-input'.)
Syntax:
_regexp-break <filename>:<linenum>:<colnum>
main.c:12:21 // Break at line 12 and column 21 of main.c
...
(lldb) apropos breakpoint
b -- List all breakpoints, or set a breakpoint using
one of several shorthand formats.
```
