A formatting test for David Winterbottom: improving commandlinefu for submitters

Commandlinefu.com is great but has a few bugs when people are submitting new commands: . 1. There is no preview button. This was a minor inconvenience before, but now is a major problem since new commands won't show up to be edited until they have been moderated. . 2. White space in the description field and in the comments is almost completely lost. People resort to using periods in between paragraphs to force a line break. Indentation of code is ridiculous. . 3. Many characters get munged. . 3a. For example, a less than character in the description gets read as an HTML tag and discarded. In order to type a less than, I've had to type "<" (I hope that comes out right). Unfortunately, when re-editing a command, the HTML entity is turned into a literal less than character, which I have to change back by hand before saving. 3b. Some unicode characters work in the description field, but turn into ugly literal HTML strings when put in the sample output or in an additional command using the $ prefix. . For example, here is a unicode character: ❥ Here is the same character after a dollar sign: ❥ . 3c. Some unicode characters don't work anywhere. Bizarrely, it appears to be the most commonly needed ones, such as Latin-1 accented characters. Here are some examples, . Bullet: ?, Center dot: ?, Umlaut u: ?. . 4. Here is an example of the greater than, >, and less than, . 5. Commandlinefu used to abbreviate long descriptions on the front page and had a "more..." button so that people could read the rest if they wanted. That's a good feature as it encourages people to explain their commands more fully. Either, the feature has gone missing, or, perhaps, I was just hallucinating it existed in the first place. If the former, please bring it back, If the latter, please implement this great new feature I just thought up. . 6. Tags cannot include Unicode characters. If you try to type one in, the cursor will just spin and spin as it attempt to look up if that tag exists already. For example, try typing Ctrl+Shift+u 2 7 6 5 SPC as a tag name.

echo "?????, these are the umlauted vowels I sing to you. Oh, and sometimes ?."
Here is U+2022: ?, which should look like a big bullet point, not an HTML entity.
