Here is a Python program that reads through the mbox-short.txt file and figures out the distribution by hour of the day for each of the messages:

```python
counts = dict()
try:
fhand = open('mbox-short.txt')
except:
print('File cannot be opened:')
exit()

for line in fhand:
if not line.startswith('From '): continue
pieces = line.split()
time = pieces[5]
hour = time.split(':')[0]
counts[hour] = counts.get(hour, 0) + 1

# Sort by hour
sorted_counts = sorted([(k,v) for k,v in counts.items()])

for hour, count in sorted_counts:
print(hour, count)
```

This program works as follows:

1. It first tries to open the file 'mbox-short.txt'. If the file cannot be opened, it prints an error message and exits.
2. It then reads through each line in the file.
3. If a line does not start with 'From ', it skips to the next line.
4. If a line does start with 'From ', it splits the line into pieces using spaces as the delimiter.
5. It then gets the time from the 6th piece (index 5) and splits the time into hours, minutes, and seconds using a colon as the delimiter.
6. It gets the hour (the first piece of the time split) and increments the count for that hour in the counts dictionary.
7. After going through all the lines, it sorts the counts dictionary by hour.
8. Finally, it prints the counts for each hour, sorted by hour.
