It is assumed that debug statements always print a newline, fix two
missing ones.

Prior to this patch the first and the last error encountered during
parsing are printed. To see other errors verbose needs
enabling. Unfortunately this can drop useful errors, in particular on
terms. This patch changes the errors so that instead of the first and
last all errors are recorded and printed, the underlying data
structure is changed to a list.
Before:
```
$ perf stat -e 'slots/edge=2/' true
event syntax error: 'slots/edge=2/'
\___ Bad event or PMU
Unable to find PMU or event on a PMU of 'slots'
Initial error:
event syntax error: 'slots/edge=2/'
\___ Cannot find PMU `slots'. Missing kernel support?
Run 'perf list' for a list of valid events
Usage: perf stat [<options>] [<command>]
-e, --event <event> event selector. use 'perf list' to list available events
```
After:
```
$ perf stat -e 'slots/edge=2/' true
event syntax error: 'slots/edge=2/'
\___ Bad event or PMU
Unable to find PMU or event on a PMU of 'slots'
event syntax error: 'slots/edge=2/'
\___ value too big for format (edge), maximum is 1
event syntax error: 'slots/edge=2/'
\___ Cannot find PMU `slots'. Missing kernel support?
Run 'perf list' for a list of valid events
Usage: perf stat [<options>] [<command>]
-e, --event <event> event selector. use 'perf list' to list available events
```
